Service Life predicting method and system for machine and vulnerable component of generating set

Abstract

The invention relates to a system for estimating the life of the mechanical and electrical wearing parts for the power set, which comprises a database, a server, a software, a knowledge base, a man-machine interface, and a user terminal system, the life estimation method comprises: counting the history data of the life of the mechanical and electrical wearing parts, setting up a life database of the mechanical and electrical wearing parts, determining the distribution category and parameters of the mechanical and electrical wearing parts, counting the reliability R(t) of the mechanical and electrical wearing parts, counting the reliable life tRO of the mechanical and electrical wearing parts, setting up a knowledge base of the malfunction result of the mechanical and electrical wearing parts, determining the changeover period HRP of the mechanical and electrical wearing parts, estimating the residual life HRL, adjusting the planned maintenance interval to realize the optimized maintenance. The advantages of the invention are that the changeover period of the mechanical and electrical wearing parts can be calculated quantitatively in the using stage of the power set, and the residual life of the parts can be calculated quantitatively, thereby a computer online monitor of the changeover period and the residual life of the mechanical and electrical wearing parts can be realized.

Description

technical field [0001] The invention relates to a method and system for life prediction of mechanical and electrical vulnerable parts of a generator set, which is applied to the replacement and maintenance of mechanical and electrical vulnerable parts of mechanical equipment and electrical equipment of a generator set, and belongs to power generation engineering and generator sets technology field. Background technique [0002] The mechanical and electrical equipment of the generator set has a large number of mechanical and electrical wearing parts. The mechanical and electrical wearing parts refer to the parts that frequently fail in power plants and are often replaced or repaired in planned maintenance and accident maintenance. The replacement or maintenance of the mechanical and electrical vulnerable parts of the existing generator sets is mostly replaced or repaired in the planned maintenance based on experience, or replaced or repaired after the mechanical and electrica...

Problems solved by technology

Replacement or maintenance of mechanical and electrical wearing parts after failure may cause large economic losses

According to experience, replace or overhaul the mechanical and electrical wearing parts in advance during the planned maintenance of the generator set. It may be replaced too early, and the remaining life of these mechanical and electrical wearing parts will not be fully used, resulting in waste and economic losses.

At present, there is no suitable method and system available for the life prediction and replacement cycle determination of the mechanical and electrical wearing parts of the generator set
